Our Chris sources tell us he's now enforcing a strict guest policy at his Calabasas mansion - and letting everyone in his crew know he's as serious as death ... no more randoms allowed. We told he's pulling back on parties for starters, but there's this problem with his 2 roommates/best friends. They now have to submit a guest list to Chris IN WRITING, and they must describe who they are with sufficient details so he can decide whether he wants them in his home. (TMZ)

"They asked me what I think about Chris Brown," P said in a new viral video. "I like the little homie. All the money you got, man, pay for you and 'No' man and get rid of some of these 'Yes' men. If I was your big homie, I would have brought the same ol' faithful broad to you every time, just change the wig. You don't need all the new people around you. I don't care if you're an athlete or or entertainer, man, you're going to spend more money on lawyer fees. Get you a real OG, somebody that's about something real and will tell you something and teach you something and be able to tell you 'No' sometimes. Sometimes you just gotta be able to say 'No' to your homies. ... It's going to cost you more in lawyer fees. Get rid of some of them trashy broads. That broad remind me of the one Kobe had in Colorado. Trash man."

Amid hourly updates on his gun threat arrest last week, Brown unleashed his new "What Would You Do" song.
